The pump's air intake is filtered by a rotating screen or the vehicle air filter to exclude dirt particles large enough to damage the system. Air is delivered under light pressure to the injection point(s). A check valve prevents exhaust forcing its way back through the air injection system, which would damage the pump and other components.
One of the first-developed exhaust emission control systems is secondary air injection. Originally, this system was used to inject air into the engine's exhaust ports to provide oxygen so unburned and partially burned hydrocarbons in the exhaust would finish burning. Air injection is now used to support the catalytic converter's oxidation ...
This increased the available oxygen, allowing the catalyst to function as intended. Some three-way catalytic converter systems have air injection systems with the air injected between the first (NO x reduction) and second (HC and CO oxidation) stages of the converter. As in two-way converters, this injected air provides oxygen for the oxidation ...
EGR has nothing to do with oil vapor re-routing from a positive crankcase ventilation system (PCV) system, as the latter is only there to reduce oil vapor emissions, and can be present on engines with or without any EGR system. However, the tripartite mixture resulting from employing both EGR and PCV in an engine (i.e. exhaust gas, fresh air ...
This engine is equipped with secondary air injection, and is flex-fuel capable. It is entirely different from the Iron Duke, and was the last North American iteration of the GM 122 engine. The 2200 uses an iron block and aluminum two-valve cylinder head. Output is 120 hp (89 kW) at 5000 rpm and 140 lb⋅ft (190 N⋅m) at 3600 rpm.
Suspects discovered by police in Edge at Lowry Apartments. During the torture, the armed individuals went back to the man and woman's apartment and burglarized it, Chamberlain said.
Just after winning a gold medal in the individual vault final in Paris on Aug. 3, Biles spoke during a press conference about the future of her signature vault. "This is my last, definitely ...
Indiana may not have been one of the very best teams in college football, but a team that goes 11-1 in a power conference was always going to be a foregone conclusion to make the 12-team College ...
